It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The processing device 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices.
In one embodiment, as shown in fig. 2, there is provided a vibration source detecting method including the steps of:
The single-peak curve is used for reflecting the mathematical relation between time and vibration magnitude, the vibration sensor comprises at least one of a vibration displacement sensor, a vibration speed sensor and a vibration acceleration sensor which are used for recording vibration signals or converting the vibration signals into electric signals, the vibration sensor records and stores vibration data by taking voltage or current as characteristic parameters, and the vibration sensor can continuously record more than 24 hours.
The vibration sensor can be arranged on a transformer base of a public power distribution room, can also be arranged on a wall of the public power distribution room, and can also be arranged on a wall or a floor in a house.
And 204, determining the correlation between the public power distribution room and the vibration in the household according to the single-peak curve.
After obtaining a single-peak curve, the curve can be analyzed separately from the time correlation and the extreme value correlation, and specifically, two modes are as follows.
And time correlation, namely, the correlation between the vibration variation trend of the public power distribution room and the vibration variation trend of the residential house at daytime and night can be analyzed according to the single-peak curve. Specifically, the vibration variation trends of the public power distribution room and the residential house in the day and at night can be analyzed according to the single-peak curve, and when the matching degree of the vibration variation trends of the public power distribution room and the residential house in the day and at night exceeds a first preset threshold, the public power distribution room and the vibration in the residential house are determined to have correlation.
For example, as shown in fig. 3, fig. 3 is a schematic time-frequency diagram of vibration of a public power distribution room in the vibration source detection method in an embodiment, the vibration of the transformer base shows obvious periodicity, main frequency components are concentrated in 100-500 Hz, increase by a multiple of 50Hz, vibration of 200Hz is most obvious, and the amplitude is about 1m/s2. As shown in fig. 4, fig. 4 is a schematic diagram of vibration time and frequency in a household of a household in the vibration source detection method in the embodiment, vibration of a floor of the household is very complex, contains a large amount of low-frequency noise, and vibration between 100 to 500Hz is close to vibration components of a base of a transformer, but has a small amplitude not exceeding 0.01m/s2The main vibration frequency is 50Hz, and the amplitude is about 0.02-0.03 m/s2. For another example, if it is found that the vibration variation trend of the utility distribution room is the same as the vibration variation trend of the household room by 80% or more, it can be determined that the vibrations of the utility distribution room and the household room are correlated in time. Of course, the 80% is a predetermined value, and can be set to different values, such as 50% to 100%, according to different situations.
And determining the relevance between the public power distribution room and the vibration in the residential house according to the position and the time of the occurrence of the extreme value of the single-peak curve. Specifically, the locations and times of the extreme values of the single-peak curve may be compared, and if the similarity between the locations and times of the extreme values of the vibrations in the public power distribution room and the household room on the single-peak curve exceeds a second preset threshold, it is determined that there is a correlation between the vibrations in the public power distribution room and the household room.
For example, as shown in FIG. 3, the vibration of the transformer base shows a significant periodicity, with the main frequency components concentrated at 100-500 Hz, increased by a factor of 50Hz, and the vibration at 200Hz is most significant, with an amplitude of about 1m/s2. As shown in FIG. 4, the vibration of the household floor is very complex, contains a large amount of low-frequency noise, and the vibration between 100 Hz and 500Hz is close to the vibration component of the transformer base, but the amplitude is very small and is not more than 0.01m/s2The main vibration frequency is 50Hz, and the amplitude is about 0.02-0.03 m/s2. And alsoFor example, if the similarity between the position and time of an extreme value of the vibration in the public power distribution room and the household room appearing on the single-peak curve exceeds 80%, it is determined that there is a correlation between the vibration in the public power distribution room and the household room. Of course, the 80% is a predetermined value, and can be set to different values, such as 50% to 100%, according to different situations.
And step 206, selecting and performing FFT (fast Fourier transform) on the multi-section vibration data in the public power distribution room and the household according to the single-peak curve, and determining the relevance between the vibration in the public power distribution room and the household from the obtained frequency domain graph.
Alternatively, after the association is determined, it may be determined that the utility distribution room is associated with a vibration source in the household, and at this time, a reasonable solution may be proposed for the association and executed to suppress vibration of the utility distribution room.
It should be noted that after the vibration data are acquired and FFT-transformed, frequency domain graphs corresponding to respective multiple sections of vibration data of the public power distribution room and the household can be obtained, that is, the correlation between the two in the frequency domain can be analyzed, and whether the two have the correlation can be known through analyzing the frequency domain graphs. Specifically, when the frequency component matching degree of the multi-section vibration in the public power distribution room and the household room on the frequency domain graph exceeds 80%, the public power distribution room and the household room are determined to have correlation. Of course, the 80% is a predetermined value, and can be set to different values, such as 50% to 100%, according to different situations.
It can be seen that the application is based on the long-time continuous measurement of the vibration of the public power distribution room and the residents, a single-peak value curve is generated according to the measured vibration data, then corresponding Pe and A sound level curves are determined, and the correlation of the vibration source in the public power distribution room and the residents is determined by combining data analysis and characteristic parameter comparison, so that whether the vibration source is the transformer of the public power distribution room or not is determined.
It should be understood that, although the steps in the flowchart of fig. 2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 2 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
It should be noted that, in the present application, three determination methods may be combined for determination, that is, the time correlation, the extremum correlation, and the frequency domain correlation are integrated at the same time, and only when the three methods are satisfied at the same time, it can be determined that the vibration source in the public power distribution room and the vibration source in the household have a correlation. Referring to fig. 4, fig. 4 is a diagram illustrating an embodiment of a vibration source detection method according to an embodiment of the present disclosure.
First, vibration sensors are disposed at predetermined locations of transformers in a utility power distribution room and in a house of a resident.
And then, connecting a measuring line, setting sampling frequency and sampling time, continuously measuring, storing data, sorting the stored data, drawing a single-peak curve of long-time vibration, and accordingly intercepting the data for further processing.
